Whakaoti mō B
\left\{\begin{matrix}B=-\frac{A}{C}\text{, }&C\neq 0\\B\in \mathrm{R}\text{, }&A=0\text{ and }C=0\end{matrix}\right.
Whakaoti mō A
A=-BC
Tohaina
Kua tāruatia ki te papatopenga
BC=-A
Tangohia te A mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
CB=-A
He hanga arowhānui tō te whārite.
\frac{CB}{C}=-\frac{A}{C}
Whakawehea ngā taha e rua ki te C.
B=-\frac{A}{C}
Mā te whakawehe ki te C ka wetekia te whakareanga ki te C.
A=-BC
Tangohia te BC mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
